NOTE:
After a power supply is powered on, it can take up to 60 seconds
for status indicators—such as the LEDs on the power supply, the command
output displays, and messages on the LCD display on the craft
interface—to indicate that the power supply is functioning normally. Ignore
error indicators that appear during the first 60 seconds.
5.
Verify that the
CB ON
LEDs on the power supply faceplate are lit steadily, indicating
that the circuit breakers are on.
6.
Verify that the
DC OK
LED on the power supply faceplate is lit steadily, indicating that
the power supply is correctly installed and is functioning properly. The
DC OK
LED
blinks momentarily, then lights steadily.

Replacing a Cable Restraint on a TX Matrix Three-Input 240-A DC Power Supply
Each three-input 240-A power supply is shipped with the standard cable restraint shown
in Figure 130 on page 284. Two optional cable restraints are shipped in the accessory box.
If your DC power cables are too large or inflexible to fit into the standard cable restraint,
we recommend that you remove the standard cable restraint and install the optional
cable restraint (see Figure 131 on page 284) on each three-input 240-A power supply.
NOTE:
Before you remove a chassis from a rack or cabinet, you must remove
the optional cable restraint from the three-input 240-A power supply.
